人工智能开发系列(3) YOLOV3开发与实现

我执行./darknet detector test train_my_data/voc.data train_my_data/yolov3-tiny-modify.cfg train_my_data/backup/yolov3-tiny-modify_900.weights train_my_data/train_images/000937.jpg -thresh 0.1
后，报错如下
Loading weights from train_my_data/backup/yolov3-tiny-modify_900.weights...Couldn't open file: train_my_data/backup/yolov3-tiny-modify_900.weights
我应该怎么保存我自己训练的权重？
